Mundorf L125 air core coil, 3.9mH ±2%, 0.75ohm, 1.25mm OFC-copper wire, Ø70xH29mm

Mundorf's L series uses a 99.99% solid OFC round copper conductor, specially developed for high quality filtering. The winding stand is made of glass fiber reinforced plastic. The L-series coil is the standard for quality passive filtering.

Mundorf CFC16 air copper foil coil, 8.2mH ±2%, 1.31ohm, 17x0.07mm OFC-copper wire, Ø108xH24mm, with backed varnish wire

La bobine série CFC est une self à air constituée d’un enroulement de feuille de cuivre OFC 99.99% séparé par une feuille d’isolation polypropylène de 0.02 mm. La partie centrale est percée pour la fixation.

Mundorf BL71 air core coil, 22mH ±2%, 5.26ohm, 0.71mm OFC-copper wire, Ø70xH29mm, with backed varnish wire

The BL series from Mundorf uses the same coils as the L series but with the addition of a stabilization varnish considerably reducing electromagnetically induced vibrations. If your passive filter concerns a high-end speaker, the choice of a BL coil instead of an L coil is a relevant choice because it directly impacts the listening quality.

Mundorf L100 air core coil, 1.2mH ±2%, 0.55ohm, 1.00mm OFC-copper wire, Ø58xH18mm

Mundorf's L series uses a 99.99% solid OFC round copper conductor, specially developed for high quality filtering. The winding stand is made of glass fiber reinforced plastic. The L-series coil is the standard for quality passive filtering.

iCore feron coil Mundorf BS140, 10mH ±3%, 0.35ohm, 130x35xH35mm

Mundorf's BS series uses a solid 99.99% OFC copper round conductor stabilized by varnish, wrapped around a rod-shaped iron-silicon alloy core. Each end of the stick is fitted with a hole for attachment.

Mundorf P71 ferrite pipe core coil, 2.7mH ±3%, 1.01ohm, 0.71mm OFC-copper wire, Ø40xH23mm

Mundorf's P series is halfway between the L and H series, with a ferrite core (or aronit for larger models) to find a compromise between low internal resistance, small footprint and price. Ideal in car-audio or sound system.

Mundorf H125 ferrite core coil, 1mH ±3%, 0.11ohm, 1.25mm OFC-copper wire, Ø35xH25mm

MCoil Drum-Core coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

Air core coil Mundorf BL140, 12mH ±2%, 1.35ohm, 89x76xH61mm, with backed varnish

The BL series from Mundorf uses the same coils as the L series but with the addition of a stabilization varnish considerably reducing electromagnetically induced vibrations. If your passive filter concerns a high-end speaker, the choice of a BL coil instead of an L coil is a relevant choice because it directly impacts the listening quality.
